Y., ACORPORATION OF NEW YORK SELF-LIGHTING CIGARETTE AND IGNITION BANDTHEREFOR Application filedflctober 30, 1925, Serial No. 65,723. RenewedNovember 15, 1930.

My invention relates to new and useful improvements in self-lightingcigarettes and.

ignition bands therefor. The object of my invention is to provide anignition band suit 5 able for application to the lighting end of acigarette which will enable the cigarette to be lighted by striking sameupon a suitable abrasive surface.

In my invention, I associate with a cellulose or fibrous substance suchas paper with an additional oxidizing substance and provide the samewith a layer of a fulminating material. This fulminating substance ismade preferably with a nitrocellulose solu-v tion base, as the same thenhas desirable waterproofing qualities. Preferably,

also, I employ on the side of the paper opposite to the fulminatingsurface an adhesive,

and I have found that a suitable adhesive may be formed ofnitrocellulose solution, which not only-will function as an adhesive inafiixing the ignition band to the end of the cigarette, but is itself aready transmitter of combustion and self-combustible.

I thus provide a fuse band which may be prepared in ribbon form andwhich may be applied by suitable mechanism in strips to the en of thecigarettes. The ignition band can be prepared economically, and is ofitself sufiiciently flexible to permit being prepared in ribbon form andafiixed to the cigarette wrapping paper either before or after the samehas been filled with-tobacco and rolled into cigarettes. ,The-adhesive,ifni- 85 trocellulose solution or similar substance be used, will be ofa substance not homogeneous with the paper base. Thus when the adhesiveis touchedwith' a solvent, it will function as an adhesive withouttending to unduly soften 40 the band itself. The band preferably isapplied tp the outside of the cigarette and will have on its exteriorsurface a layer of a'ful- -minating substance. When this is contactedwith suitable abrasive surfaces, it will ignite the paper, Which willburn readily, being im-i pregnated with an oxidizing substance. Thepaper has the necessary coal-forming properties to surround thecigarette and the to bacco filling at its end with a ring of fire,

and thereby to ignite'same in an even manner.

My invention consists of the novel devices described herein and shown,but it is to be understood that I have set forth my invention in itspreferred form and the scope of the invention is not to be understood aslimited to the form described but is as set forth in the claims appendedhereto.

Of the drawings,

Figure 1 is a view of a self-lighting cigarette provided with mypreferred form of ignition band;

Fig. 2 is an enlarged detail and illustrative end view of same; and

Fig. 3 is a view of a section of my ignition band prepared in ribbonform prior to being afiixed to cigarette wrapping paper.

In preparing my self-lighting cigarettes and ignition band to be affixedthereto, I

take, preferably, a cellulose isolated from wood, such as a filterpaper, and submit same to an extra oxidizing substance, preferably byireating the paper with a ten per cent dilute solution of potassiumnitrate. This impregnation may be accomplished either when the paper isbeing made or after it has been made. Sheets of paper thus prepared,free from all moisture, are then coated with a fulminating substancewhich isspread on .thinly over the entire surface. If it is desired toapply adhesive at that stage in the operation, an adhesive may be spreadover the reverse side of the treated paper. I have found thatnitrocellulose solution serves admirably as an adhesive for thispurpose. It also moistureproofs the side of the paper to which is hasbeen applied. If the fulminating substance likewise is prepared with abase of nitrocellulose solution and is spread on the other side of thepaper as described,.both side-s of the paper thus will be treated withamoistureproofing dope. The treated paper and the entire ignition bandtherefore will be rendered. impervious to moisture, and, when applied tocigarettes, will make the self-lighting qualities of the cigaretteslasting and permanent.

The paper, when spread with fulniinate and with adhesive as abovedescribed, may' then be cut into suitable strips of desirable width andlength and pasted around the cigarette wrapper at intervals so as tocome out at the end of the cigarette when rolled and cut.

In the drawings, a cigarette of the usual from is shown composedofcigarette wrapping paper 1 with tobacco-filled center 2. At

the lighting end of the cigarette is exteriorly applied an ignition band3. This ignition band is composed of a thin layer of fulminatingsubstance 4 which preferably should have as a base for mixing thefulminating materials a nitrocellulose solution or similar substancewhich is self-combustible and has desirable waterproofing qualities. Theignition band has a base made of paper or otherisimilar material 5,'andthe band is aflixed to the cigarette paper by adhesive 6. This adhesiveis made of nitrocellulose solution which is a self-combustible materialand a transmitter of combustion, which therefore aids the oxidized paperbase in its function of igniting the cigarette. The ignition band may beprepared -pri or to its application to the cigarette as above describedand may consist of a ribbon"? which is formed with an oxidized paperbase and a fulminate layer on one side.

- Preferably, also, the ribbon may be provided amount of solvent to theadhesive.

with a layer of adhesive 4 and, as stated, nitrocellulose 'solutionismost suitable for this purpose 'of the adhesive. The ribbon thusprepared is flexible and may be wound onsuitable reels or bobbins suchas 8. The ribbon is ready prepared and may be applied to the cigaretteby merely applying a slight This solvent will not permeate the entireband,

as the paper base and the adhesive will not be of homogeneous materials.

,I have described and shown my ignition band used'and adapted to be usedwith selflighting cigarettes. It'is, of course, equally suitable for usewith cigars and little cigars,

and it is also to be understood that it is capable of being used in manyother ways, and

that my invention is not to be considered as limited to the particularuse described What I claim is new and desire to secure by United StatesLetters Patent is 1.
